Question

In a pipe of 90 mm diameter water is flowing with a mcan velocity
of 2 ms and at a gauge pressure 350 KN m2. Determine the total
head, if the pipe is 8 meters above
the datum line Neglect friction​

Answer 1

Answer:

In a pipe of 90mm diameter water is flowing with a mean velocity of 2m/s and at a gauge pressure of 350KN/m^(2)

Answer 2

The total Kinetic Head will be 0.204 meters.

Given: Diameter = 90 mm = 0.09 m

Mean velocity = 2 m/s

Gauge Pressure = $350 N/m^2$

We need to compute the Total kinetic head where the pipe is 8 meters above the datum line.

Explanation:-

• This question will hold the concept of Bernoulli's Theorem.

• Bernoulli's Equation is given by:

       -$\frac{P}{pg}+\frac{V^{2}}{2g}+Z=constant$

        where $\frac{P}{pg}=PressureHead$, $\frac{V^2}{2g}=Kinetic Head$$Z=DatumLine$

• Now, the Total Kinetic Head will be $\frac{V^2}{2g}$  = 0.204 metre
